Topic: Which Arduino Should I Buy? (Read 5 times) previous topic - next topic

Hi everyone, I'm a grade 11 student in computer engineering. We are using the PICAXE 28x1 and I don't much care for it:
Question 1: What is a micrcontroller do you recommend for me?
Question 2: What microcontroller do professionals use?

I've been doing research and there are so many times. I've been looking at the Arduino Uno Rev3 and then there is this other one that seems like the exact same thing for cheaper. What is the difference? See the links below

Then there are all these other ones etc. etc. complicated, ugh. Help would be greatly appreciated!!

Those are the same - just a different package for the microcontroller.
Use the first one - when you damage it, you can replace the chip & still use the board.
Buy a spare 20 MHz Atmega328P-PU at the same time if you can.

I use that chip and Atmega1284P-PU (DIP) and -AU(quad flat pack) in a lot of boards - browse my signature link.

Woah, big words there, heh.

I suppose the Atmega328P-PU is the actual microcontroller. This is the 20MHz one right? See link.

And the  Atmega1284P-PU is just a bigger, better microcontroller that professionals use correct? Can install it on the board that comes with
Arduino Uno Rev 3 package? Link to purchase it please? I couldn't find it.

The quad flatpack I have no idea what that is. Wikipedia was confusing, heh.

And I'm new here so I don't know what a signature is and how to browse it. Sorry.

But other than that, thanks a lot for your help. I will definitely buy the Arduino Rev 3 if you suggest it.
I suppose the only difference between the two links is that the Rev 3 can be easily "repaired" if you break it, correct?

Yes, Atmega328P-PU is the actual microcontroller.  They are available as 10MHz and 20MHz parts.

Note that this one does not  have a bootloader installed.
You can use the Arduino you buy to install one.
Or you can buy one with the bootloader installed.

The DIP package can be easily replaced, the quad flat pack not so much. Quad flat package just describes the part package.

"Professionals" use both. Depends on the project need. I use both. I use the ATmega2560 also, you can find that microcontroller on the Mega board.
